Thinking of building 2 to 4 Tuba 24 for DJ Rig and wanted to use my PLX3602 to power.
Will switching on back of amp for 33HZ cut and sub 100Hz cut be good? Trying to replace SRS1500 Mackies for better and more bass and don't want to run a seperate xover if possible. Tops are JBL MRX 515 with MP425 xovers and powered by PLX2502. Any thoughts would be great.

Those switch positions will work for the amp. I'm not too clear about the crossover for the tops. What's the specifics of the MP425 crossover and what's the -3dB point for the MRX's?

It'll get you through until you can spring for a formal active crossover which will afford you a little more flexibility in deploying your gear, especially if whatever you end up includes a built-in PEQ.
